.To all 'whom z may concern:

Be it known that l, (lus'rav Kommun, a citizen of the United Stat-es,residing at St. Louis, Missouri, have invented a certain new and usefulImprovement in Truck Side Frames. of `which the following is a full,clear, and exact description, such as will enable others skilled in theart to which it appe'rtains to make and use the same. v 1 his inventionrelates to truck side frames of the type in which the journal boxes aredivided or formed in two parts, one part of each journal box usuallybeing cast integral with the side tra-me 'and the other part beineremovable so that the wheelaxles with the wheels thereon can be runlongitudinally out ot the truck without disconnecting the AIO sideframes from the other parts of the truck. Y

One object of my invention is to provide a side i'ralne of the typereferred to in which the journal. boxes are so designed that it is notnecessary to use telt or a similar packing material between theeoperating parts of the box in order to insure dust and oiltight joints.

Another. object is to provide a truck side trarne which is so designedthat the lower parts of the journal boxes cannot drop oft' or becomecompletely detached from the top parts of the boxes in case the meansthat holds the two parts of the box together breaks or becomes lostwhile the truck is in service.

@ther objects and desirable features of my invention will be hereinafterpointed out.

Figure 1 ont the drawings is a side elevational view of a portion ot acar truck side trarne constructed in accordance with my invention; Fig.2 is a horizontal sectional View taken on the line 22 of Fig. 1; Fig. 3is a vertical transverse sectional view taken on the line 33 of Fig'. 1.

leterrirnfg` to the drawings which illus trate the preferred form of myinvention. A designates a car truck side :trame provided ithhorizontally divided journal boxes, each of which comprises a stationarytop part 1 that is preferably formed integral with the side frame, and aremovable lower part 2 that is'v detachably connected to the upper partof the box, thereby enabling the side trames of the truck to be jackeduphigh enough to permit the wheel axles with the wheels thereon to berun longitudinally ont of the truck after the lower parts v'of thejournal boxes have been removed. The stationary top part l of the box ispreferably provided with integral side lugs or stops 3 that coperatiewith the usual 'lugs bn 'the side of the journal bearing, not shown, andalso with stops 4 that coperate with the journal bearing wedge, notshown, so that the top part ot' the journal box will receive all of theside shocks and end thrusts to which the journal bearing is subjectedwhen in service. The removable lower art 2 of the box is substantiallysemicy indrcal Ashaped in cross section, as shown in Fig'. 1,

and it is provided at its upper end with laterally projecting* flangesor ears 5 that receive removable fastening devices 6 which pass througha laterally projectingl ear Y 'on the top part 1 of the boxand ahorizontally disposed flange 8 on the side traine located adjacent thelower edge of the top part l of the box, as shown in Figs. 1 and 2j saidfasteningdevices actingto retain the lower part oi. the box in operativeposition.

ln order to insure tight joints between the top and bottom parts ot thejournal box without using telt or a similar packing material I haveprovided the lower part 2 of the'box with upwardly projecting flanges orportionst)v that project upwardly into the top' part 1 of the box andlap over the lower edge portions of the side walls of said top partv 1,said flanges 9 being offset inwardly slightly with relation to the sideWalls of the lower part 2 of the box so as to form shoulders on whichthe lower edges of the side walls of the top part 1 bear when theremovable part 2 of the box is in operative po'sition, as shown in Fig.2. In other words, the upper edges of the side walls 2 of the removablelower part of the box bear against the lower edges of the sidewalls ofthe .stationary top part l, and theupwardly projecting flanges 9 'onsaid lower part 2 project upwardly beyond the joints between said edgesso as to prevent the oil' inside of the box `from escaping through said,joints or tionary top part of the box, as shown in fulllines in Fig. land in broken lines in Fig. .8, said lugs or stops ll projecting intosaid slots so as to prevent the lower part 2 of the box from droppingoil or becoming completely detached from the top part 1 in case thefastening devices 6 break or become lost when the truck is in service.ln order to eliminate the possibility of the oil escaping through theslots 10 and the flanges 9 I have provided the flanges 9 with integralpockets `bayonet-shaped slots 10.

12 which are arranged on the inner sides of said flanges 9, as shownclearly in Fig. 3. After the fastening devices G have been removed thelower part 2 of the box can be moved outwardly toward the left, lookingat Fig. 3, far enough to bring the open ends of the slots 10 intovertical alinement with the inwardly projecting lugs 11 on the top partof the box and thus permit the bottom part 2 to be moved downwardly outof engage nent with the stationary top part 1 of the In assembling thebox the removable bottom part 2 is arranged under the top part 1 andthe-n moved upwardly so that the inwardly projecting lugs l1 on saidto'p part will project into `the bayonet-shaped slots 10 and the flanges9. Thereafter, the removable bottom part 2 of the box is moved to theright, looking at Fig. 3, so as to position the. lugs 11 at the innerends of the Finally, the fastening devices 6 are rinserted so as toretain the removable bottom part 2 o'f the box in operative. position.lf the fastening de'- vices 6 should break or become lost while thetruck is in service the bottom part 2 of the box would merely dropdownwardly a slight distance but. would not become completely Separatedfrom the top part of the box owing to the fact that the lugs 11 projectinto the slbts in the langes 9, and in view of the fact that said slotsare substantially 4bayonet-shaped, as shown in Fig. 3, it would beimpossible for the bottom part 2 of the box to move outwardly or to theleft in Fig. 3 after the lugs 11 had entered the recesses at the innerends of the slots 10.

' A side frame of the construction abovedescribed comprises-few partsand is in expens1ve to manufacture; the journal-boxesthe meeting edgesof said' parts; and still another desirable feature, of such aconstrucvent the bottom part from dropping ed in case said fasteninglmeans breaks or hemmen.
